Comment (by pramsey):

 Third option, from convo in hackers:

 * Using MemoryContextRegisterResetCallback on a AllocSetContext created
 under our PortalContext should do the trick, with less direct mucking
 about into the internals of contexts.

 Only good for 9.5+, and might need some massaging to still work with old
 cache scheme.
